With a wealth of previously unseen clips, a jumpy energy and a good soundtrack, the four-part "Sex: The Revolution" (VH1, 10 p.m.) stands out from the usual VH1 programming by actually taking its subject seriously.

There's a lot of blurring of nudity (using a new technique that turns skin tones into subtle woven patterns). An uncensored version of the four-part documentary will be shown next week on Sundance.

REMOTE PATROL

In part one of a two-part finale on "House" (Fox, 9 p.m.), the good doctor is in a bus accident and suffers amnesia, spending the rest of the time piecing together the four hours he lost. Or how he got in the strip bar.

If you were never a fan of "Idol" contestant Ace Young, you may want to watch him get killed on "Bones" (Fox, 8 p.m.). He's acting!

A new season of "American Gladiators" (NBC, 8 p.m.) includes a few new gladiators (including the two who won last season) and some new games, including Rocketball and Vertigo, the latter being a metaphor for current TV quality.

If she's on the screen twice as long as she was in her original cameo, Britney Spears may last 5 minutes on "How I Met Your Mother" (CBS, 8:30 p.m.).

The Brit Matt Grant has to choose between Chelsea and the girl-child (and daughter of Lorenzo Llamas) Shayne on the finale of "The Bachelor" (ABC, 10:02 p.m.). Unlike last season, he might actually pick one.

The season finale of "The Hills" (MTV, 10 p.m.) is turned into a nightlong event with a "Live From the Hills Season Finale" (MTV, 9 p.m.) pre-show and an after-show at 11 p.m.

It all leads into a new spin-off series of another MTV franchise, "My Super Sweet 16 Presents: Exiled" (MTV, 11:30 p.m.), in which brats from previous seasons are sent to "primitive tribes around the world."
